the KOM chair by elem is created using an incremental sheet forming process

elem — a berlin based industrial design studio — has presented its conception for a lightweight and stylish reinterpretation of an archetypal metal chair, with a focus on versatility and stability. called the KOM chair, the bright red seat was created with the support of the fraunhofer institute, a german society for the advancement of applied research.

elem constructed the chair using lightweight, 20mm aluminum tube framing with a fitted aluminum seat and backrest forming a sturdy and stable compound. the shells of the chair are slightly moulded and correspond perfectly with the curves of the spine, resulting in a seamless, fluid frame. KOM’s plain and minimal appearance underlines its universal character, making it ideal for a broad range of living situations.

the technology used to produce the shells is know as incremental sheet forming, or ISF. in the ISF process, a computer controlled tool outlines the contours of the desired shape onto a flat sheet. after each completed circuit the tool descends slightly, slowly forming the frame of the piece without the use of a mold. this technology keeps costs and weight down as it doesn’t require a substructure for support or any additional tools for production, making it ideal for smaller series and on-demand production.

the result is a smooth, streamlined and sturdy chair whose vibrant block color and defined silhouette suggests a bright and buoyant piece.
